Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The real-time monitoring device for grounding resistance of the present invention is composed of five parts, namely: a switching power supply, a ZIGBEE system, an AC pulse constant current source, a data acquisition processing unit, and a data array unit.

[0021] Specifically: the switching power supply can process the mains power into 5V, and output 1A to power the entire system.

[0022] The ZIGBEE system can generate excitation signals, process received data signals, and display and transmit data.

[0023] The AC pulse constant current source can amplify, isolate and filter the excitation signal generated by the ZIGBEE system and output it to the data array unit.

[0024] The acquisition data processing unit can collect, filter, and reshape the voltage obtained between the voltage test electrode and the test ground pile after the signal emitted by the cur...

Abstract

The invention relates to a ground resistance real-time monitoring device, which comprises a switching power supply, a ZIGBEE system, an AC pulse constant current source, a collected data processing unit and a data array unit. According to the ground resistance real-time monitoring device, current emitter poles and voltage test poles adopt an anti-corrosion high-conductivity material, and are buried underground permanently; and when ground resistance change surpasses requirement, an alarm can be given, and the test data is transmitted to a client data center through a network. According to the ground resistance real-time monitoring device, during early-stage construction, the current emitter poles and the voltage test poles for testing are pre-buried in groups according to environment and geographical positions at that time, and thus collection of test data at different positions can be finished through one test. The ground resistance real-time monitoring device can reflect the ground resistance of a grounding grid comprehensively.

Description

technical field [0001] The invention relates to the technical field of real-time monitoring, in particular to a real-time monitoring device for grounding resistance. Background technique [0002] At present, many electrical equipment industries have different requirements for grounding resistance in various industries. The general practice is to make a grounding grid that meets the required grounding resistance during construction. The test electrode of the ground resistance tester is taken up after the test is completed. It is only a single measurement, not a continuous test every day. After passing the measurement at that time, the test was basically not carried out. But in fact, grounding resistance varies with climate, time, and soil. When the grounding resistance becomes large, it is very unfavorable to the normal use of electrical equipment, and even damages the electronic equipment. Contents of the invention [0003] The invention aims to solve the technical prob...
